If you're struggling to entertain a group of bored kids on a rainy day, cracking open a K'NEX kit is bound to go down a treat. The brightly coloured interlocking pieces let you build creative, and often elaborate, models. The individual cogs, wheels, rods and pieces found in K'NEX kits satisfyingly click together. Kids can build freely, or follow a specific model, so it's an easy way to keep children occupied for endless hours. Or of course nostalgic adults who fondly remember past creations can get stuck in too.


We've included a range of fun kits, from quirky modes of transport and googly eyed dinosaurs, to functioning six-foot Ferris wheels. You'll also find a couple of Kid K'NEX kits for younger children so everyone can get involved.
